Hi there I've been having intermittent problems with my rear brakes. I have a 2013 diesel router. At 37000 miles I had the rear discs and pads replaced when I had a knocking sound investigated. Every 200 or so miles a loud knocking sound would appear, quite often when driving on the straight, and would disappear after 5 or so minutes. Rear nearside disc read hot. Dealers response, warped discs. I tried to argue fault find the cause but it was put down to wear and tear.
Now at 62000 miles and I have a intermittent running sound again from the rear on some downhill from braking and right hand turns . This time it's after 40 or so miles I.e. when brakes are warm.
My thought is the caliper is sticking so if like to strip and regrease the pads and pistons. Any guides on this as it seems a job I can do. I luckily have friends with experience of doing this but not on Hyundai.
Specifically on a 2013 can the piston just be pushed back in or does it need wound back.
Ate there any guides on removing the pads as some show clips others not. As I say I would not be attempting this alone but would like as much info as possible
